Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing nearby without mechanical contact by using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner area of the mobile terminal covered by the touch screen described above or in the vicinity of the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. If the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of a conductive object as a change in electric field according to the proximity of the object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, an action of approaching a touch screen without contacting an object to recognize that the object is located on the touch screen is referred to as a "proximity touch", and the touch An act of actually touching an object on a screen is called a "contact touch". The location at which an object is proximity-touched on the touch screen means a location at which the object corresponds vertically to the touch screen when the object is proximity-touched. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) there is. Meanwhile, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and proximity touch pattern detected through the proximity sensor 141, and furthermore, visual information corresponding to the processed data.

Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

As such, when there is a touch input to the touch sensor, the corresponding signal(s) is sent to the touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the controller 180. Thus, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or the same control according to the type of the touch object that touches the touch screen (or a touch key provided other than the touch screen). Whether to perform different controls or the same control according to the type of the touch object may be determined according to an operating state of the mobile terminal 100 or an application program currently being executed.

Meanwhile, the controller 180 may calculate the location of the wave generating source through information detected by the optical sensor and the plurality of ultrasonic sensors. The position of the wave generating source can be calculated using the property that light is much faster than ultrasonic waves, that is, the time for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the location of the wave generating source may be calculated by using light as a reference signal and a time difference between the arrival time of ultrasonic waves.

Meanwhile, looking at the configuration of the input unit 120, the camera 121 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

A photo sensor may be stacked on a display device, and the photo sensor is configured to scan a motion of a sensing target close to the touch screen. More specifically, the photo sensor scans the content placed on the photo sensor by mounting photo diodes and transistors (TRs) in rows/columns and using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing object according to the change in light, and through this, the location information of the sensing object can be obtained.

The display unit 151 displays (outputs) information processed by the mobile terminal 100 . For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to such execution screen information. .

The strength and pattern of the vibration generated by the haptic module 153 may be controlled by a user's selection or a setting of a controller. For example, the haptic module 153 may synthesize and output different vibrations or sequentially output them.

In addition to vibration, the haptic module 153 responds to stimuli such as an array of pins that move vertically with respect to the contact skin surface, air blowing force or suction force through a nozzle or suction port, rubbing against the skin surface, electrode contact, and electrostatic force. It is possible to generate various tactile effects, such as the effect of heat absorption and the effect of reproducing the feeling of coolness and warmth using an element capable of absorbing heat or generating heat.

Furthermore, although each drawing has been divided and described for convenience of description, it is also possible to design to implement a new embodiment by merging the embodiments described in each drawing.

5 is a flowchart illustrating an embodiment of controlling a display device in a mobile terminal according to an embodiment of the present invention. Hereinafter, each step of FIG. 6 described may be controlled by the controller 180 of FIG. 1A or the controller 240 of FIG. 2 .

In step S501, the mobile terminal may be booted.

In step S502, when the mobile terminal is booted, it may be determined whether the mobile terminal is a device supporting multi-display. Here, whether multi-display is supported can be determined based on whether the mobile terminal can control one or more displays.

In addition, in step S502, an embodiment of determining whether the mobile terminal is a multi-display supporting device when the mobile terminal is booted has been described, but after the mobile terminal is booted, the mobile terminal is also a multi-display supporting device. Of course, it is possible to determine whether it is recognized or not. That is, the timing of determining whether the mobile terminal is a device supporting multi-display is not limited to one embodiment.

If the mobile terminal is a device that does not support multi-display, in step S503, the mobile terminal may skip the multi-input process. More specifically, if the mobile terminal is a device that does not support multi-display, two or more input processes may not be created.

If the mobile terminal is a device supporting multi-display, in step S504, the mobile terminal may create a first input process and a second input process. A first input process and a second input process may be created. Here, the first input process may correspond to the input management service 310 described above with reference to FIG. 3 , and the second input process may correspond to the multi-client input management service 320 .

More specifically, when the mobile terminal is a device supporting multi-display, a plurality of input processes may be generated because the mobile terminal needs to control two or more display units of the mobile terminal or display units of other devices. In this case, the first input process may correspond to a process of outputting the first input unit in the mobile terminal, and the second input process may correspond to a process of controlling the second input unit to be output.

In step S505, when the first input process and the second input process are generated, the mobile terminal may register the first input process and the second input process with the system server. More specifically, the mobile terminal may register with the system server that a first input process for outputting an IME application in the mobile terminal is generated and a second input process for outputting a multi-client IME application in a display device is generated. .

In step S506, a situation in which the output of the input device to the first display unit is required may occur. More specifically, the situation in which the output of the input device is required on the first display unit may mean a case where the mobile terminal receives a signal requesting an output of the input device from the user. For example, the mobile terminal may receive a touch signal for touching a user input window being output on the main display from the user.

In step S507, the mobile terminal may output the first input device to the first display unit. In one embodiment of the present invention, the mobile terminal may output the first input device to the first display unit when receiving a signal requesting output of the input device from the user. For example, when receiving a touch signal for touching a user input window from a user, the mobile terminal may output the first input device to the main display accordingly.

In step S508, a situation in which the output of the input device to another display unit is required may occur. More specifically, the situation in which the output of the input device is required on another display unit may mean a case in which a signal requesting the output of the input unit is received from a user in a display unit other than the first display unit in step S506. . For example, the display device may receive a touch signal for touching a user input window output to the second display unit of the display device from the user. Or, for another example, the mobile terminal may receive a touch signal for touching a user input window output on the cover display from the user.

If step S508 is not performed, in an embodiment of the present invention, step S507 may be returned.

In step S509, the mobile terminal can check identification information of the display when receiving a signal from the display device. Here, the signal received by the mobile terminal may include a signal requesting an output of an input device in another display unit.

More specifically, when receiving a request signal to output an input device from another display unit, the mobile terminal can check the identification information of the display that transmitted the signal. At this time, since all displays can have a unique identification number, the mobile terminal can check the identification information of the display.

If the identification information of the display is confirmed through step S509, the mobile terminal may output the first input device in step S510 or the second input device in step S511.

More specifically, in step S510, the mobile terminal may output the first input unit through identification information of the display when another display unit requiring output of the input unit is a display inside the mobile terminal. For example, the mobile terminal may output the first input device on the cover display when receiving an input device output request signal from the cover display while the first input device is output on the main display.

Also, in step S511, the mobile terminal may control to output the second input unit through identification information of the display when another display unit requiring output of the input unit is an external display of the mobile terminal.

More specifically, in step S511, if the other display unit requiring output of the input unit through the identification information of the display is the display of the display device, the mobile terminal outputs the second input unit on the second display unit of the display device. You can control it. For example, when the mobile terminal receives an output request signal of the input device from the monitor of the display device in a state where the first input device is output on the main display, the mobile terminal may output the second input device on the monitor.

Accordingly, the user of the mobile terminal can use the existing UX as it is by using the first input device when using the display in the mobile terminal.

Also, the user of the mobile terminal can use the second input device output from the display device simultaneously with using the first input device.

In step S610, the mobile terminal may create a first input process and a second input process. In one embodiment of the present invention, the mobile terminal can generate the first input process and the second input process only when the mobile terminal is a device supporting multi-display.

In step S620, the mobile terminal may output the first input device to the first display unit based on the first input process.

In step S630, the mobile terminal may receive a first signal from the display device. Here, the first signal may include a control signal to output the input unit in the display device.

In step S640, the mobile terminal may output the second input unit to the second display unit of the display device according to the first signal. Here, the second input unit may be output based on the second input process.
